Government guidelines on using phones at the wheel says that it is illegal to use a mobile while driving, or riding a motorcycle - and the rules are the same if you're stopped at traffic lights or queuing in traffic.

Motorists can be slapped with six penalty points and a £200 fine if caught.

A London Ambulance Service spokesperson said: "We have looked into this incident and are following our disciplinary process. We believe this is an isolated incident and does not reflect the high driving standards of our staff."

Earlier this year it was reported cops might be able to confiscate people's phones to discourage them from talking on the phone while driving.
